The card text of Medium of the Ice Barrier goes like this:
"If your opponent controls 4 or more cards than you do, you can Special Summon this card from your hand."
I am not sure what this means. Does it mean that the opponent must control
a)exactly 4 cards
or b)more cards than you do in order to summon it?
